I would like you to know how happy you have made me with the selection of aircraft engine and frame. I am building the same combination but behind you a few weeks. I had just started looking at the firewall design changes needed when I was called out of town for business. Setting here in a hotel this evening decided to look for some ideas and found the excellent work you have posted. I will be sending results from my work to compare but it won't be for a couple of weeks because I have to get back from this trip. Thanks again for posting.
